The second trailer for Pacific Rim Uprising debuted a ton of new footage, but also showcased more polished CGI effects. One complaint some fans expressed after the first Uprising trailer debuted was that the Jaegers looked "too clean" and moved "too quickly".

Despite all that, the new trailer did debut some not-so-polished Jaegers - battle damage littered the bunch and as you can see by the comparisons below, the overall CGI was given a dramatic upgrade as well:
